Study of Partial Replacement of Fine Aggregate by Oyster Shell and Partial Replacement of Cement by Rice Husk Ash

Abstract

Due to the excessive usage and consumption of the conventional building materials, these are not the sustainable or feasible source for building. Hence, we must provide the alternative building material. Some of the conventional building materials are sand, gravel, cement, etc.. It may seem difficult to provide replacements to these existent and traditional medium or to change the common notion about these conventional materials as human co-existed and practiced using them since early ages. But the provision of ‘alternative materials’ must be made feasible and widely usable by the designers and developers. For this, incentives like cost-effectiveness, resourcefulness and easier availability of the ‘alternative materials’ must be emphasized promptly. The use of waste product and agricultural byproducts are very constructive. As per the current research and statistics, the precise amount of RHA has been used which is amalgamated with cement in meticulous quantity. After that the fine aggregate of above admixture is replaced by Oyster Shell. For regularly used concrete, Indian Standards (IS) methods are applied as the parameters for the mix design. As per the reference and basis of IS method, mix design has been as the replacement of alternative materials that is Rice Husk Ash and Oyster Shell. For the pragmatic usage of these new, unconventional and much needed materials, we need to create such meticulous model. Here, In this case we aim to cast the concrete in substitution of RHA in most advantageous way.
